CVE-2026-20795 - Vulnerability Details

- Improper Buffer Restrictions Leading to DoS in Intel PROSet/Wireless WiFi Software Drivers

Description

Improper buffer restrictions for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.

Analysis

Impact

This vulnerability arises from improper buffer restrictions in the Intel PROSet/Wireless WiFi Software device drivers running in Ring 2. An attacker can send crafted network packets that trigger a buffer overflow or similar memory corruption, leading to a denial of service. The flaw causes loss of availability of the affected system; there is no impact on confidentiality or integrity.

Affected Systems

Affected systems are Windows machines running the Intel PROSet/Wireless WiFi Software for Windows. Specific version information is not provided, so all versions that include the vulnerable drivers should be considered.

Risk and Exploitability

The CVSS score is 7.1, indicating a moderate to high severity. With an EPSS score of less than 1% the likelihood of exploitation is low, and the vulnerability is not currently listed in the CISA KEV catalog. The attack can be carried out by a network adversary with no authentication and low complexity, and does not require user interaction, which makes it potentially exploitable with standard network tools.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
